Trun your Github Issue into kanban with greasemonkey & Gira

I found Github Issues kind of really powerful but lack of one feature -- kanban,
so I wrote this simple javascript within greasemonkey to add kanban feature to it.

it simply add kanban view in Github Issues and make all issues draggable.

it really solve my problem of manage github issues, make it more visualize to me.
